1 is OK (the bass is a little much for me), 2 is good, 3 could use some bottom end but defiantly do that one, 4 is good, I like 5, but I think it could use a little more "Aphex Twin" randomness, I LOVE 6 but the bass needs to be constantly playing and warping, and 7 is cool, but for the most part I love all of them so go for it
I made progress with every track, but I ran into some problems: No intro for 7, I feel nothing when I hear 3, ... 1 needs a slow part in it. So probably 1 first
